30Nm, then crosswise with 70Nm.
2. Before starting up leave the pressure control valve in the
open position for about 2 minutes while the motor is run-
ning (bleeds the unit). Only then close it until the noise of
the inlet valve can be heard.

10.8 TYPICAL WEAR PARTS
Despite the use of high-quality materials the highly abrasive
e ect of the paints means that wear can occur at the following
parts:
Inlet valve (spare part Order No.: 0344700)
For replacing refer to Section 10.2
(failure becomes noticeable through performance loss and/or
poor or no suction)
Outlet valve (spare part Order No.: 0341702)
For replacing refer to Section 10.3
(failure becomes noticeable through performance loss and/
or poor suction) The outlet valve is usually considerably more
durable than the inlet valve. Thorough cleaning may already
help here.
Relief valve (spare part Order No.: 0169248)
For replacing refer to Section 10.5
(failure is noticeable through performance loss. Furthermore
material arrives constantly at the return hose although the
multifunction switch is set to spraying.
This part is relatively seldom a wear part.
1. Remove the cover (1) (a screwdriver may be helpfull to
move the cover back from the box).
2. Loosen the cable threaded joint (2).
3. Loosen the wires in the mains terminal (3) .
4. Replace the unit connecting line.
(only an approved power cable with the designation H07-
RNF with a splash-proof plug may be used).
5. Connect the green/yellow wire to the contact with the PE
sign.
6. Connect the cover again with the earthing plug for the
heating hose and mount it carefully (do not squeeze any
cables!)
